Problems solved by technology

[0004] In the wireless power transmission technology according to the prior art, there are many limitations for smoothly performing charging
That is, when transmitting and receiving power wirelessly, there are limitations such as limited transmission distance, restrictive positional relationship between transmitter and receiver, etc.
Therefore, there is a limitation that wireless charging can be performed only when the wireless power receiver is in a specific direction or in a specific position relative to the wireless power transmitter

Abstract

The present invention provides a wireless power transmitter and a wireless charging system using the wireless power transmitter. The wireless power transmitter may be electromagnetically coupled to a receiving coil of a wireless power receiver to wirelessly provide power, and includes a substantially planar transmitting core. The transmitting coil has a plurality of windings and is arranged on the surface of the transmitting core. The transmitting core can extend beyond the transmitting coil in the planar direction.

Description

[0001] This application claims the priority and benefit of Korean Patent Application No. 10-2014-0059265 and No. 10-2014-0189109 filed in the Korean Intellectual Property Office on May 16, 2014 and December 24, 2014, respectively. The disclosures of these Korean applications are hereby incorporated by reference for all purposes. technical field [0002] The present disclosure relates to a wireless power transmitter and a wireless charging system using the same. Background technique [0003] According to the development of wireless technology, various wireless functions from data transmission to power transmission have become feasible. A wireless charging method for charging various portable devices in a non-contact manner has attracted attention. [0004] In the wireless power transmission technology according to the related art, there are many limitations on smoothly performing charging. That is, when power is transmitted and received wirelessly, there are limitations suc...
